Application filed August 5, 1926. Serial No. 127,229.

Our invention relates to plasteners and particularly to refrigerator door fasteners.

One oi the objects elf our invention is the provision of a door :tas'teners which may be readily operated from the inside oil: a re- :t'rigerator, cooler or the like, a Well as from the outside, to actuate the fastener bolt in. the closing or the opening of the deer.

Another object of the invention is to provide a lastener oi the above-mentioned character which has constant tension applied to hold the door tightly closed.

Another object which we have in view is a fastener of such construction that should the inside handle he accidentally broken oil a person locked in a retrigerator could push the door open and thereby save himself from :lreezin g.

ll; vrther object o'li ourinvention is to pro vide a rot rator door it: stener which may he applied to either rightor left hand doors.

it still thither object to provide adjust able means for the fastener to accommodate doors of dillerent thicknesses.

Our invention possesses other objects and features of advantage, sonic oi? which with the foregoing will be set forth in the iollowing description of the invention which is illustrated in the drawings accompanying and liorn'iing part oi. the specification. It is to be understood that we do not limit ourselves to the showing made by the said desci-notion and drawings, as we may adopt varying lorins ol? our invention within the scope of the appended claims to this specilication. Our preilerred construction of the invention. illustrated in the accompanying drawings, in which Figure 1 a. perspective view oi the fas tener as seen from the outsideoi a refrigerator, the door and jainb of the latter be ing shown fragmentary.

Fig. is a median horiaoijital sectional view of the :lfastener of Fig. 1 drawn to a larger scale. Certain parts are shown. in tall including the bolt which is withdrawn suflieiently to allow the door to open.

Fig. 3 is a median longitudinal vertical sectional view of the .i astener, the bolt being shown in its projected position and in full lines.

Fig. it is a t'aesverse vertical sectional housing adapted to be secured to the outside oi. a door. A spring-pressed bolt is slidably mounted in the housing so asto extend out of one end thereof, and means are provided both on the inside and the outside of the door for withdrawing the bolt against the tension of the spring so that the fastener may be released from either side oil the door to ell'ect an entrance to or egress from the refrigerator.

For convenience and simplicity we shall. refer to a. refrigerator as being the object to which our :tastener is applied, but it is to be understood that it is within. the purview of the invention to be applied wherever useful and desirable.

ill [ore specifically, our invention comprises a. housing 6, preferably of malleable iron, and iforn'ied with a flange 7, whereby the housing may be secured to the outside oi? the door 8. The end walls 9 and 11 of the housing are formed with bearings 12 and 1.3 respec-tively and in whichis slidably mounted a latch-bolt l l. The end 16 of the latch-- bolt is preferably :torlred to support a. roller 17. Extending through the latch-bolt 1d and within the housing a stop pin 18, which forms a. tulcruin for the operating levers of the device and also limits the move ment of the bolt.

Coiled loosely around the bolt 1 1 and dis posed between the wall 11 and the pin 18, is a spring 19 which tends to maintain the bolt in extended position. A lever 21 on the out side of the housing is pivoted to lugs 22 formed integralwith the housing, and is provided with a forked end 23 which extends ment with the roller 17 on the bolt 14. I The edge 31 functions with the bolt to hold the door tightly closed even though the door shrinks in time.

Mounted in a substantially vertical position within the housing is a shoe 32, adapted to slide freely over the coil spring 19. One end 33 of the shoe is forked so as to engage the stop pin 18', the forked end 33 of the sliding shoe being preferably wider than the forked end23' of the lever 21, so as to engage the extreme ends of the pin 18. The other end of the shoe is provided with an outwardly extending lip 34- by which the shoe may be drawn lengthwise of the housing. Secured to the inside face of the housing is a plate 36 having a boss Journalled in the boss is a hub 38 formed integral with a cam 39 disposed within the housing and engageable with the lip 34. The hub 38 is provided with a preferably hexagonal socket 39, ill-'WlllCll' is seated and secured at one end by the machine bolt'41,

: a hexagonal rod 42, which extends through the door 8. The other end of the rod 42 is supported in a collar 43 journalled in a on the inside of the door so that when it is desired to open toe door from the inside of therefrigerator, the lever 46 may be turned to cause the cam 39 to engage the lip 34 on the sliding shoe 32 and draw the shoe towards the end 11 of the housing. It will be observed that the shoe in so being moved, brings with it the latch-bolt 14 acting against the tension of the spring. When the lever 46 is released the spring 19 automatically forces the bolt back to its extended position. When it is desired to open the refrigerator door from the outside, the outside hand lever 21 is drawn outwardly from the door in the direction indicated by the arrow 47 shown in Fi g. 2, and when the lever 21 is released the spring 19 functions as before'described.

So that our improved fastener may be mounted on doors of various thicknesses.

we make the hexagonal rod 42 of ample length, and the handle adjustable thereon by means of the screws 48, so that should the rod extend beyond the lever 46 when the fastener is installed, such extension may be readily sawed off. I

It is tov be observed that the shoe carries two outwardly extending lips 34 and 34,

' and that the cam 39 has two chamicred edges 5 and 5 cngageable by the said lips. This double feature provides for the application of the fastener to right and lcft-hand swinging doors by simply reversing the fastener 180 degrees.

Having now described our invention what we claim as new and desire to secure by Letters Patent of the United States of America, is
